Description

Function Documentation

__STATIC_INLINE void SCB_DisableICache

(

void

)

The function turns off the instruction cache.

__STATIC_INLINE void SCB_EnableICache

(

void

)

The function turns on the instruction cache.

Note

Before enabling the instruction cache, you must invalidate (SCB_InvalidateICache) the entire instruction cache if external memory might have changed since the cache was disabled.

After reset, you must invalidate (SCB_InvalidateICache) each cache before enabling it.

__STATIC_INLINE void SCB_InvalidateICache

(

void

)

The function invalidates the instruction cache. The instruction cache is never dirty so cache RAM errors are always recoverable by invalidating the cache and retrying the instruction.

Note

After reset, you must invalidate each cache before enabling (SCB_EnableICache) it.
